The new intelligent addressable open class visual alarm device (CASB393) combines the high output sound of the wall sounders with a brighter LED. It is compliant to EN54-23, 3 and 17 making it suitable for use as a Fire notification device within Europe.

The CASB393 offers low current consumption, maximising the number of devices that can be fitted on a loop and provides a flexible solution due to it soft addressing, multiple tone and body options.

The open class VAD comes in two variants, the standard CASB393 and the weatherproof CASB393WP, which is IP66 rated meaning it is ideal for outdoor locations.

With both variants, the open class VAD is suitable for all markets where EN54-23 VADs are now a requirement.
